Body tissue that supports and holds body structures together
A crack or break in bone
The area in which the brain rests
Tissues that are characterized by cells that are embedded in large amounts of inter-cellular substance
The area that surrounds and protects the spinal cord
A sheet of internal muscle that extends across the bottom of the ribcage; The diaphragm separates the thoracic cavity from the abdominal cavity and performs an important function in respiration
Chest cavity; cavity in the vertebrate body enclosed by the ribs between the diaphragm and the neck and containing the lungs and heart
Contains organs of the digestive, reproductive, and excretory systems

The lacy network of connective tissue in the center of the bone
The tough outer membrane of a bone
Hard, dense bone composing the outer cortical layer and consisting of a variety of periosteal bone, endosteal bone and haversian.
Any of the tiny, interconnecting longitudinal channels in bone tissue through which blood vessels, nerve fibers and lymphatics pass.
A living bone cell.
Comprised of bones. It provides structure; supports and protects the inner organs.
Comprised of skeletal, cardiac and smooth muscle. It provides structure; supports and moves trunk and limbs; moves substances through the body.
Comprised of skin hair and nails. It protects against pathogens; help regulate body temperature.
Comprised of the heart, blood vessels and blood. It transports nutrients and wastes to and from all body tissue.
Comprised of the air passages and lungs. It carries air into and out of the lungs, where gases (oxygen and carbon dioxide) are exchanged.
Comprised of the lymph nodes and vessels, white blood cells. It provides protection against infection and disease.
Comprised of the mouth, esophagus, stomach, liver, pancreas,small and large intestines. It stores and digests food; absorbs nutrients and eliminates waste.
Comprised of the kidneys, ureters, bladder, urethra, skin and lungs. It eliminates waste; maintains water and chemical balance.
Comprised of the brain, spinal cord, nerves, sense organs and receptors. It controls and coordinates body movements and senses; controls consciousness and creativity; helps monitor and maintain other body systems.
Comprised of glands such as adrenal, thyroid, pancreas, hypothalamus. It maintains homeostasis; regulates metabolism, water and mineral balance, growth and sexual development and reproduction.
Comprised of ovaries, uterus, mammary glands in females, testes in males. It produces ova and milk in females, sperm in males and offspring after fertilization.
The bones of the skull,ribs, spine and sternum.
The bones of the arms and legs along with the scapula, clavicle and pelvis.
The process by which cartilage slowly hardens into bone.
The site of bone elongation at the ends of long bones.
The place where two bones meet.
Prevent movement where bony plates connect; ex: the skull.
Permit limited movement; ex: bones of the vertebral column.
Enable the body to perform a wide range of movement.
Allows movement forward and backward like a hinged door, ex: elbow.
Allows up and down, forward and backward, as well as to rotate in a complete circle. ex: shoulder.
Allows you to turn your head from side to side, forward and back.
Allows you to rotate your thumbs and helps grasp objects.
Allow bones to slide over one another. ex: the joints between the small bones of your foot which allow your foot to flex when you walk.
Tough bands of connective tissue that hold the bones of the joint in place.
A lubricating substance secreted by the tissue to help protect the ends of the bones from damage by friction.
A skeletal muscle cell that runs the length of the muscle and contains many nuclei.
Develops when the immune system begins to attack body tissue.
A degenerative bone disease in which the cartilage covering the surface of the bone becomes thinner and rougher.
A dense bundle of skeletal muscle fibers.
A muscle whose movement can be consciously controlled.
A muscle whose movement cannot be consciously controlled.
A contracting thread in a skeletal muscle.
The thick protein filament of a sacromere.
A boundary of a sarcomere; point of anchor for thin actin filaments.
The basic contractile unit of skeletal and cardiac muscle that is the portion of the myofibril between two adjacent Z lines.
A tough, solid band of connective tissue that connects and supports body parts.
Attachment point of a tendon to a stationary bone.
The point where the muscle attaches to the moving bone.
A muscle that bends a joint.
A muscle that straightens a joint.
The physiological inability of a muscle to contract do to relative depletion of ATP.
The temporary lack of oxygen availability.
The outer layer of skin composed of many sheets of flattened, scaly epithelial cells.
A protein that forms hair, bird feathers, human fingernails, and the horny scales of reptiles.
